Thanks for your great work, seems like the only thing i have to change is the elite bonus and maybe point K for some skills (I was already using slightly different modifiers for some runes because i couldn't explain the numbers i got during my tests with Fraps and Vegas), but i'll check every point again.

Btw. can someone explain me why the attack speed with wizards Shock Pulse skill and 1.0 character sheet aps is ~1.08 attacks per second ?

Couldn't find anything about this skill so i had to fraps it with different attack speeds and count the frames between the attacks. I'm using 0.825 / avg attack speed because it looks like the skill has a base time for the animation which is reduced by aps. This could be completely wrong but it was very close to my true dps for all tests.

All of the above are in the "damage increased by skill" modifier group ("I" in my formula).

Done and i've added some Demon Hunter and Witch Doctor skills. Took me hours with fraps to understand how Gargantuan - Restless Giant Rune works (especially in combination with other damage increasing skills) and how to calculate the dps.

Seems like the detailed calc doesn´t take +% damage vs elites into account yet (at least my SoJ). Anyway, the main reason why I´m posting is that you have the same description for RLTW and WW dual wielding tick frequency, but they´re in fact opposites. It should be

When dual-wielding, (tornado) tick frequency depends on the attacks per second (aps) of the last weapon swung before using Sprint.
When dual-wielding, (WW) tick frequency depends on the weapon you are about to swing not the weapon you swung before using WW. (exact opposite of Sprint)

I think the calculator works correctly, just the description is wrong.

Thats strange, can you send me a msg with a link to your profile ? Everything works here: http://www.d3rawr.com/d-631sa
Same items, set 2 is without the 30% bonus from SoJ. Different skill damage, tDPS and dps vs. elite.

researched the "slain enemies rest in pieces" affix for like 5 hours until I figured it out, this one was the most difficult out of all the modifiers I researched, second place is dmg vs elites bonus

Slain enemies rest in pieces is a separate damage modifier that scales with both primary stat and critical hit damage. The modifier is ((1+ primary/100) * (1+ critical hit damage/100)). Note that this applies to a normal finishing blow, which is always "yellow". When you critically hit on the finishing blow, you also get the usual critical damage bonus on top of it.

Well, I don´t know where else to post stuff about damage calculations and game mechanics related to damage calculations. You´re right if you meant that probably very few people care about the damage you do with the 3 weapons in the game with the affix on the finishing blow and I understand if ssdraw won´t add this to his calculator, but maybe people will be able to use the post as a reference for how it works - I haven´t found anything in depth about it.

Don't know if it is useful at all but the detailed calculator got a "PvP mode" (simulates skill damage against other heroes). Take the numbers with a grain of salt because there is still a lot of research and testing required (and i have to level every class to 60 again on my other account :P)

edit: i'm working on the missing skills but it's a lot of work (i need a full day with fraps / vegas / my calculator and a lot of paper for some of them)
